The file 'Rollerstruder: Filament Feeder / Driver / Extruder 3D Printer Model' is (scad,stl) file type, size is 712.2KB.
This is the filament driver I used (together with my hobbed bolt) sucessfully on my Ultimaker for the last 10 months (and this is PLA!)
It was designed originally for 3 mm but it would work alike with 1.75 mm as it boils down to how to the hobbed bolt (I ran it successfully with ~2 mm trimmer line filament)
This thing is in progress, though it is currently revision 5.3: I just should stop spending days on it since it is extremely reliable (much more than what I had stock).
It is written with openscad and it is fully parametric (incuding height, average thickness, bearing diameters...). It also prints quickly (2-3 hours), and almost in one piece (2mm walls and 30% infill is enough as it features internal dedicated structures).
People may be interested in the unusual features I think it has. Check my blog for the details.
